TO ALL WHOM IT MAY CONCERN:

Be it known that I, E. W. PIKE, of Galesburg, in the county of Knox, and State of Illinois, have invented a new and useful Improvement in Culti'vators; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, referencebeing had to the accompanying drawings, forming part of this specification, in which- 4 Figure 1 is a side view of my' improved eultivator.

Figure 2 is a rear view of the same. Figure 3 is a detail sectionalview of the same, taken throughthe line xx, g. 1. Y Figure 4 is a detail sectional viewof lthe same, taken through the line yy, fig. 2.

My invention has for its objectv te improve the construction of W. II. Smiths cultivator, patented January 15, 1861, and numbered 31,132, so as to make it more convenient, reliable, and e'eetive in operation, andit consists -in the improvements hereinafter more fully described and set forth.

A is the beam of the cultivator, to the forward end of which the draught is applied, and to the rear end of which is attached the cross-beam B. C are brace-rods which pass through the cross-beam B, and. the forward ends of which are bolted tothe beam A, as shown iin figs. 1 and 2. D are the forward plough-standards, two of which are used, and which are bolted to and upon opposite sides of the beam A, the one somewhat in advance of the other,l

and which are strengthened by brace-,rods E, as shown in fig. 1. F are the rear or outer standards, which are.v

pivoted to the cross-beam B by bolts passing through said standards, and through the said cross-beam near its ends. Gris a cross-beam securely bolted to the beam A, at or near its middle part. H is a strengthening-brace, the ends of which are secured to the en ds of the cross-beam G, and which passes beneath and is securely bolted tothe beam A, as shown in fig. 8. The cross-beam G is further strengthened by the brace-rods I, the forward ends of which are secured to the forward part of the beam. A, and the rear ends of which pass through and are secured to the i ends of the said crossbeam G. J are swinging plates, through holes inthe centre of which the braceuods I pass, so aste pivot the said plates or bars J to the forward sides of the ends ofthe cross-beam Gr. are plates attached to the forward side of the ends of the cross-beam G, to prevent the said beam frombeing worn'by the movement of the swinging plates or bars J. L are rods, the forward ends of which have beads or buttons formedr upon them, and which pass through and are swivelledito the lower parts ofthe swinging bars or plates J. The rear ends of the rods L pass through the lower parts of the outer or rear standards, where' they are secured in` place by screw-nuts l', so that the tautness of said rods may be adjusted at pleasure. M are rods, constructed and connected with the upper parts of the plates J and standards F lin the same manner as the rods Ii are connected with the lower parts of said plates and standards. N are the handles, which are bolted to the inner sides of the upper ends of the standards F, and to the forward ends of which are attached eye-bolts n', through the eyes of which the rods M pass. O is a plate attached to the upper side of the end of the cross-beamB, the upper end of which is made circular, and is notched to receive the bolt or block 1?; the inner end. of which is pivoted between the inner ends of two jaws, R, formed upon or attached to the inner side of the plate Gr. T is a-socket attached to or formed upon the inner side of the upper part of the plate S, and in which is placed a coiled wire spring, U, the lower end of which rests'upon the upper side of the pivoted bolt or bloclt P. V is a rod, the lower end of iwhieh' is attached to the end of the bolt or block P., and the other end of which extends up into such a position that it can be conveniently operated by the ploughman. W is a plate, the lower edge of which is hinged to the upperiside of the end of the cross-beam B, and which is held forward against the standard F by the springs X attached to the said cross-beam B, and the free ends of which press against the rear side of the hinged plate W. The upper part ofthe plate W is slotted, to receive the pin Y rigidly attached to the standard F, and which enters one or the other of the said slots in the plate W. The slots of the plate W are arranged in `the arc of a circle, as shown in ig. 2,'and to the upper edge of the said plate is attached the lower end of rod Z, the upper end of which extends up into such a position as to be conveniently operated by the ploughman. By this construction the outer ploughs may be quickly and conveniently adjusted, so as to run closer `'together or further apart, so as to work as close to the plants as may be desired, or so as to avoid uneven hills.

I claim as new, and desire to secure by Letters Patent- 1. The combination of the plate S, jaws R, and coiled spring U, with the pivoted catch-block and stundard F, substantially :is herein shown arid described, and for the purpose s'et forth.

2. Thehinged plate W und springs X, in combination with the crossjbearn B and standards F, substantially as herein shown and described, and for the purpose set forth.

3. The combination of the brace-bur H withy the beam A and cross-beam G, substantially as herein shown and described, and for the purpose set forth.
